Through the overturning attaching mechanism 200, the attaching process of the membrane and the glass plate and the feeding/discharging process of the glass plate are not interfered with each other and can be carried out synchronously, so that the attaching speed of equipment is improved. The specific steps of the attaching process are as follows:

step 1: turning over the attaching mechanism to be at the 0-degree position or resetting to the 0-degree position, so that the second cavity 210b is located at a feeding station, and feeding the glass plate;

step 2: the glass positioning mechanism 100 in the second cavity 210b positions the glass plate;

and step 3: the overturning and attaching mechanism 200 overturns 180 degrees to 180 degrees; at this time, the second cavity 210b has a downward opening and is located at a fitting position, and the first cavity 210a has an upward opening and is located at a loading position;

and step 9: and (5) repeating the step (5) to the step (8).

It should be noted that, in order to reduce the possibility of bubbles existing between the film and the glass plate during the bonding process and to reduce the influence of the bubbles possibly existing on the finished product as much as possible, it is a conventional design in the art to provide a vacuum mechanism to make the bonding station in a vacuum state, and the vacuum mechanism is not improved in the present invention, and is not described again in the present invention.

As shown in fig. 5 to 8, in order to ensure the position accuracy when positioning the glass, the glass positioning plate 110 of the present invention has a rectangular shape; the glass positioning push block 130 comprises a longitudinal glass positioning push block 1301 arranged in the length direction of the glass positioning plate 110 and a transverse glass positioning push block 1302 arranged in the width direction of the glass positioning plate 110. The glass positioning plate 110 is provided with a first negative pressure hole 111, and the first negative pressure hole 111 is used for adsorbing a glass plate.

The first driving mechanism 120 comprises a longitudinal driving assembly and a transverse driving assembly 121; the transverse driving assembly 121 includes a longitudinal driving motor 1210, a first inclined pushing plate 1211, two second inclined pushing plates 1212 and a transverse guiding rail 1213; the first inclined pushing plate 1211 is connected with the driving shaft of the longitudinal driving motor 1210, and the two second inclined pushing plates 1212 are respectively connected with the transverse glass positioning pushing block 1302; the two second inclined push plates 1212 are arranged on the transverse guide rail 1213 and move along the transverse guide rail 1213; the first inclined pushing plate 1211 has two symmetrical first inclined pushing surfaces, the second inclined pushing plate 1212 has two symmetrical second inclined pushing surfaces, and the two second inclined pushing surfaces are matched with the two first inclined pushing surfaces, so that when the longitudinal driving motor 1210 pushes the first inclined pushing plate 1211, the first inclined pushing plate 1211 drives the two second inclined pushing plates 1212 to move oppositely, thereby driving the transverse glass positioning pushing block 1302 to move oppositely, so as to position and clamp the glass plate in the width direction of the glass plate.

The invention adopts an inclined plane pushing mode to realize that the positioning of the glass plate in the width direction can be completed by adopting one driving motor. When the first inclined pushing plate 1211 moves to the right under the action of the longitudinal driving motor 1210, the two first inclined surfaces push the two second inclined surfaces to drive the two second inclined pushing plates 1212 to approach each other along the transverse guide rail 1213. According to the invention, the two first inclined surfaces, the two second inclined surfaces and the two second transverse glass positioning push blocks 1302 are respectively and symmetrically arranged, so that when the longitudinal driving motor 1210 drives the first inclined push plate 1211 to move, the first inclined push plate 1211 drives the two second inclined push plates 1212 to synchronously and reversely move, and the center line of the two second inclined push plates 1212 close to each other is superposed with the bisector of the included angle formed by the two first inclined push surfaces, namely, the center line of the transverse position of the glass plate is superposed with the bisector of the included angle formed by the two first inclined push surfaces, and further, the transverse position of the glass plate relative to the glass positioning plate 110 can be controlled by adjusting the transverse relative position of the first inclined push plate 1211 and the glass positioning plate 110.

The longitudinal driving assembly is used for driving the longitudinal glass positioning push block 1301, and the longitudinal driving assembly adopts the same driving structure and driving mode as the transverse driving assembly 121, so that the longitudinal center position of the glass plate can be uniquely determined. The longitudinal driving assembly and the transverse driving assembly 121 are mutually avoided so as not to generate interference. The driving motor in the present invention can be replaced by a driving cylinder to perform a linear driving function, and it should be understood that such a replacement also falls within the protection scope of the present invention.

The central position of the glass plate positioned by the glass positioning mechanism 100 of the invention does not change along with the movement of the glass positioning push block 130, so the glass positioning mechanism 100 adopted by the invention can dynamically adapt to glass plates with different sizes, and the positions of the glass plates with different sizes can be accurately positioned at the set positions under the condition that the glass positioning mechanism 100 is not required to be adjusted.

In an embodiment of the invention, the first inclined plane and the second inclined plane may be transversely separated, when the longitudinal driving motor 1210 is reset to drive the first inclined pushing plate 1211 to reset, the two second inclined pushing plates 1212 are reset by the elastic restoring mechanism 140, that is, the elastic restoring mechanism 140 is further disposed between the two second inclined pushing plates 1212, so as to reset the two glass positioning pushing blocks 130 when the longitudinal driving motor 1210 is reset.

Referring to fig. 8, in order to reduce friction between the first inclined pushing surface and the second inclined pushing surface, in another embodiment of the present invention, a cross slide rail 1214 is disposed between the first inclined pushing surface and the second inclined pushing surface, the cross slide rail 1214 includes a first slide rail 1214a and a second slide rail 1214b, the first slide rail 1214a is fixed to the first inclined pushing surface, and the second slide rail 1214b is fixed to the second inclined pushing surface. The cross slide rail 1214 is a separate slide rail, that is, the first slide rail 1214a can be laterally separated from the second slide rail 1214b, and the first slide rail 1214a can push the second slide rail 1214b, so that the first slide rail 1214a can slide relative to the second slide rail 1214b, but when the first slide rail 1214a is reset, there is no pulling effect on the second slide rail 1214 b.

In other embodiments, the cross slide rails 1214 may also be integrated slide rails, that is, the first slide rail 1214a has both pushing and pulling effects on the second slide rail 1214b, and the first slide rail 1214a and the second slide rail 1214b can only slide relatively in the length direction thereof, and cannot be separated laterally. At this time, when the longitudinal driving motor 1210 resets to drive the first slide rail 1214a to reset, the first slide rail 1214a pulls the second slide rail 1214b, so that the second slide rail 1214b resets. The first slide rail 1214a and the second slide rail 1214b are respectively fixed on the first inclined pushing surface and the second inclined pushing surface, so that when the longitudinal driving motor 1210 is reset, the two transverse glass positioning pushing blocks 1302 are synchronously driven to reset. When the cross slide rails 1214 adopt an integrated slide rail, an elastic recovery mechanism is not required to be arranged between the two second inclined push plates 1212.

As shown in fig. 9 to 12, in order to ensure the accuracy of the bonding between the glass plate and the membrane sheet when the glass plate is accurately positioned, the glass film laminating apparatus of the present invention further includes a film positioning mechanism 300, wherein the film positioning mechanism 300 includes a film positioning plate 310, a second driving mechanism 320, and a film positioning push block 330 located around the film positioning plate 310; the membrane positioning plate 310 is rectangular, and the length and the width of the membrane positioning plate 310 are respectively the same as those of the membrane; the film positioning pushing block 330 is higher than the film positioning plate 310, and the second driving mechanism 320 is configured to drive the film positioning pushing block 330, so that the film positioning pushing block 330 clamps the film positioning plate 310, and pushes the film sheet to coincide with the film positioning plate 310 in the process of clamping the film positioning plate 310.

The size of the film positioning plate 310 adopted by the film positioning mechanism 300 of the invention can be adjusted according to the size of the film, so that the size of the film positioning plate 310 is always the same as the size of the film to be attached, and after the film is conveyed onto the film positioning plate 310, the second driving mechanism 320 drives the film positioning push block 330 to be attached to the edge of the film positioning plate 310, thereby ensuring that the edge of the film is aligned with the edge of the film positioning plate 310, and further ensuring the accuracy of the position of the film.

The membrane is made of a soft material, and in order to further ensure the consistency between the position of the membrane and the position of the membrane positioning plate 310, the membrane positioning plate 310 is further provided with a second negative pressure hole 311, and the second negative pressure hole 311 is used for adsorbing the membrane, so that the membrane is smoothly attached to the membrane positioning plate 310. Of course, the magnitude of the adsorption force of the second negative pressure hole 311 to the membrane may be adjusted, so as to ensure that the membrane is smooth and at the same time, the membrane is not deformed or wrinkled when moving on the membrane positioning plate 310 under the pushing of the membrane positioning pushing block 330.

Besides the mode of forming the second negative pressure hole 311 on the film positioning plate 310, in other embodiments, the invention can also ensure the flatness of the film by using the pressing plate 350. Specifically, the film positioning mechanism 300 further comprises a pressing plate 350, and the pressing plate 350 is movably arranged above the film positioning plate 310 up and down; the edge of the membrane positioning plate 310 is provided with a limit support 360 higher than the membrane positioning plate 310, so that the minimum distance between the pressing plate 350 and the membrane positioning plate 310 is greater than the thickness of the membrane. When the pressing plate 350 presses the film positioning plate 310 downwards, under the limiting action of the limiting support columns 360, the minimum distance between the pressing plate and the film positioning plate is that the limiting support columns 360 are higher than the film positioning plate 310, and the height is slightly larger than the thickness of the film, so that the film is enabled to keep moving smoothly under the pushing action of the film positioning pushing block 330, and the phenomenon of wrinkles or bulges is avoided. The height of the limiting support 360 can be adjusted, so that the minimum distance can be always slightly larger than the thickness of the diaphragm, and the positioning of the diaphragms with different thicknesses is adapted. For example, when the thickness of the diaphragm is 0.5mm, the height of the position-limiting support 360 may be adjusted to make the minimum distance between 0.55mm and 1.5mm, and further, the minimum distance is preferably set to be between 0.7 mm and 1.0mm, that is, the protruding height of the position-limiting support 360 is 0.2mm to 0.5mm larger than the thickness of the diaphragm.

The membrane positioning pushing blocks 330 may be provided in four groups, which are respectively located around the membrane positioning plate 310, or may be provided in two groups, where the two groups of membrane positioning pushing blocks 330 are located on two adjacent sides of the membrane positioning plate 310.

The second driving mechanism 320 may adopt a plurality of driving motors, so that each driving motor correspondingly drives one group of the film positioning pushing blocks 330, or adopt a linkage mechanism, and one driving motor is arranged to synchronously drive all or part of the film positioning pushing blocks 330.

In this embodiment, the cylinder body of the longitudinal cylinder 321 is slidably disposed on the slide rail and connected to the longitudinal film positioning push block 331; the driving shaft of the longitudinal cylinder 321 is connected with the other longitudinal film positioning push block 331. The two longitudinal film positioning pushing blocks 331 can be driven by the longitudinal air cylinder 321 to approach or separate from each other, and meanwhile, the two longitudinal film positioning pushing blocks 331 and the longitudinal air cylinder 321 as a whole can slide left and right on the longitudinal slide rail 322.
